TolZVwhomz'tmag/concem: i' I Y Be it known that I, FREDERICK HAGGER HEADLEY, a subject ofthe King of Great Britain, residing at Kingscroft, 53,1o0dlands Road, Northfield, Birmingham, in the county of Warwick, England, have invented Improvements in `Spring `Suspension Mechanism forVehicles, of which the following is a specification. l

This invention comprises'a spring suspension mechanism for vehicles, particularly applicable to perambulators, andthe like, in which fore and rear axles extending across the vehicle are each carried by radius arms, one on each side of the vehicle, rigidly secured to the axle, and in which the radius arms at the rear of the vehicle extend rearwardly from their axis to .the rear axle of the vehicle, and those in the fore part of the vehicle extend forwardly from their axis to the fore axle of the vehicle.l

In order that this invention may be clearly understood'and readily carried into practice,

reference may bevhad to the appended explanatory sheet of drawings, upon which:-

' Figure 1 is a side elevation of a perambul lator according to this invention.

Figure 2 is an inverted-plan of certain parts shown in Figure l.

Figure 3 1s a detail perspective view show-` ing the method of mounting the springs.

' Figure 4 is a detail perspective view of a modification of this invention.

In aconvenient embodiment ofthe present invention, I pro-vide a perambulator having A a frame formed with horizontal side stays or limbs l, to which latter at a midposition in their length are pivotally connected the extremities ofthe arms `of two U-members a at positions in proximity to each otherfthe transverse parts 2 of which two U-members a are secured to the axles 9 and 9a respectively of the fore vandv rear wheels 3, 4 of the perambulator. Between these transverse parts 2 of the U-members a or adjacent rigid parts appertaining thereto `and the perambulator frame, springs 5 `are incorporated. These springs 5 are advantageously of the coiled type, being located vone on each side of the perambulator. at front and rear.

At the bottom the springs 5 are appropriately secured to a transverse stay member 6 which is bent at right angles at each extremity and-bolted, riveted or otherwise rigidly `securedvtorthe Aarms Tof the U'membe1"s a,

and being secured at the top'to a bracket or angle piece 8 which is inturn secured to the framemembers 1.'

In the modification shown in-Figure 4, the transverse part of each U-rnember may comprise the stay 6a bent at rightangles at each extremityand bolted, riveted, or otherwise rigidly securedfto the end of a stay 7 which forms'the arm of the U-member. axle l0 may rigidly be carried by this side stay 7 ata 'positionfn'ear to its connection with the said transverse stay 6. t

If desired, three or more springs may be provided in connection with the U-members, in which case the brackets 8 may be dispensed with and Ia transverse member, similar to the member 6, is secured to the frame l and the tops of the springs secured thereto.

The bodyof theperambulator may be collapsible, so that by the present invention a semi-collapsible perambulator is provided in which the wheels lare sprung or resiliently suspended in a particularly effectual manner.

YWhat I claim as my invention and desire to 1secIure by Letters, atent is axles, U-members lhaving transverse portions secured to theaxles and havingv end vpor- Ltions which form vradius arms arranged longitudinally of ther vehicle, the radiusarms of the front members extending rearwardly and being pivotally mounted on the chassis,

and those of the rear member extending for. wardly and being pivotally mounted on the The wheell n a vehicle, a chassis, front and rear thereof and the other pair rearwardly from i `the .pivotal connection thereof, front and rear pairs of Wheels, axle membersvupon which said wheels are rotatably mounted, said axle members being connected to the outer ends of the respective radius arms-at points transversely inward of the wheel positions, and springs interposed between the frame and the other parts yieldingly to resist movement ofsaid parts relative to the frame.

3. In a perambul'ator the combination of a frame having side portions, two pairs o1 radius arms, transverse members extending between and connecting said radius arms, each pair being pivotally carried at one end by the frame and one pair extending forwardly from the pivotal connection thereof land, the other pair rearwardly from the pivotal connection' thereof, a-unitary front axle transversely positioned beneath the front of the frame and a unitary rear axle'transversely positioned beneath the reary of the frame, wheels rotatably mounted upon the outer end portions of said unitary axles, theV outer ends of the front pair of the radius arms being connected to the front' axle inwardly of the wheel positionsrthereon and the outer end of the rear pair of radius arms being connected to the rear axle inwardly of the wheel posltion thereon, and

rotatably mounted, vsaid :1.Xleinembers'being.

connected tothe outer ends of the respective radius arms at points transversely inward of theA Wheel positions, and springs` interposed between the frame and the'other part-s yieldingly to resist movement of said parts rela-v tive to the frame.

In witness whereof I have hereunto set my hand. .v
